What Does It Mean If Subscriber Cannot Be Reached?

Sending messages to subscribers who don’t respond can be frustrating and confusing, yet understanding why this occurs can provide valuable insight. There may be several causes behind it and taking measures to prevent future occurrence is key to staying effective at marketing your services effectively.

Possible Reasons There could be many causes why a subscriber might not be reachable; here are some of the more likely ones:

Subscriber email address is incorrect

This is usually the cause of this error, so double-check that your subscriber’s email address is accurate by sending yourself a test message to check.

Their email address may have been blocked.

Some email providers restrict messages sent from certain senders or domains; if you suspect this may be the case for one of your subscribers, reach out to their provider and see if their address has been blocked.
Subscriber’s Email Server Is Down** If a subscriber’s email server is down, they won’t be able to receive messages and you can check its status by visiting their provider’s website.
Subscriber’s Inbox Is Full**If the subscriber’s inbox is full, they won’t be able to receive new messages from you. In this situation, ask them to empty out or create a new inbox – either way the solution lies within them!

Your Subscriber has unsubscribed from your list

If a subscriber has unsubscribed from your list, they won’t receive messages from you anymore and it is best to utilize a list management tool in order to check whether or not this person has done so.

Prevent It From Happening Again

Once you’ve identified the cause of the error, take steps to prevent it from recurring again. Here are a few strategies:

  • Incorporate a double opt-in process. When people sign up for your list, require them to confirm their email address before being added. This way, only valid email addresses will end up on your mailing list.
  • Clear Your List Regularly. Regularly remove inactive subscribers from your list in order to keep it healthy and prevent errors. * Utilize a Spam Filter. Spam filters can help protect messages from being blocked by email providers.
  • Pretest Your Messages Before Sending Them. It is always wise to test messages prior to sending them out in bulk, this way any errors can be caught more quickly and ensure your messages reach their destinations efficiently.
